ATTACHMENT FOR FURNACES.

Specification of Letters Patent.

Application filed January 26, 1916. Serial No. 74,399.

To all whom it may concern:

Be it known that I, ENOCH J. KUBIQHEK,

a citizen of the United States, residing at Horton, in the county ofBrown and State of Kansas, have invented certaln new and usefulImprovements in Attachments for Furnaces, of which the following is aspecification.

My invention relates to furnaces and has for its object the provision ofa simple apparatus which may be easilyapplied to any furnace and by theuse of which the smoke and soot usually accompanying the kindling offires and the replenishing of fuel thereon will be eliminated.

A further object of the invention is to provide a device for the statedpurpose which will be simple in construction and, therefore, easilyrenewed or repaired and which will be found efficient in operation andeconomical in production and maintenance.

' The several stated objects and such other objects as will incidentallyappear in the following description are attained in such a device as isillustrated in the accompanying drawings and the invention resides incertain novel features which will be particularly pointed out in theclaims following the description.

In the annexed drawings: Figure 1 is a view partly in transverse sectionand partly in end elevation showing a steam boiler furnace having myimproved device applied thereto; Fig. 2 is a vertical longitudinalsection of the same; Fig. 3 is an enlarged detail vertical section of myimproved attachment; Fig. 4 is a detail perspective view of a portion ofthe attachment.

In carrying out my invention, I secure in the wall of the furnace at apoint which will be in communication with the ash pit, a casing 1 whichmay be of any suitable durable material and which is preferably ofmetal. Preferably, the casing is secured in the side wall of the furnacejust below the grate bars, as shown in the accompanying drawings,although it may be applied at other points, and the casing may be of anydesired dimensions or shape as may be necessary to conform to theparticular construction of the furnace to which it is applied. The innerand outer sides of this casing are open and near the inner side thereof,I secure across the casing a partition or support 2 which is providedwith a number of openings in which are secured the tapered nozzles 3which are so disposed that their smaller ends will be directed inwardlyto the ash pit. Between the partition or sup-' port 2 and the outer endof the casing 1, I provide partitions or supports 4: which'are spacedapart to admitair into the outer wider ends of the nozzle 3 and in thesaid partitions or supports 4, I secure a plurality of nozzles 55.corresponding in form and construction to the nozzles 3-, and eachaxially alined with one of the nozzles 3. It will be easily understoodthat, when the nozzles are axially alined, the smaller end of the outernozzle will be disposed adjacent the larger end of the inner nozzle andpreferably will extend into the inner nozzle, as shown clearly in Fig. 3of the drawings. Upon the front and rear sides of the casing 1, adjacentthe lower end thereof, I secure brackets 6 in which are mounted the endsof a supply pipe 7. The ends of this pipe are closed by suitable caps orotherwise and preferably the pipe is constructed of two members unitedat their inner ends by a T-coupling 8 which also receives a member ofthe main supply pipe 9 which extends to the steam space of the boilerand may be equipped with a cutoff valve 10*. The supply pipe 9isconstructed of a series of alined members con-v nected by couplings10, as will be readily understood and passes through a loop or retainer11 secured upon the top of the casing 1 at the outer side of the same.Each coupling 10 is disposed in the plane of'two Patented Dec. 119,1916.

alined nozzles 3 and 5 and the branch supply pipes 7 leading from thecouplings are each constructed with a plurality of jets 12 which areaxially alined with adjacent nozzles and extend into the outer ends ofthe same, as clearly shown. A coupling 13 is disposed immediately abovethe loop or retainer 11 so as to connect the adjacent sections of themain supply pipe and this construction will permit the lower portion ofthe main supply pipe, with all the branch pipes extending therefrom, tobe; swung downwardly about the brackets 6 as a pivotal center so as topermit access to all the jets and to all the nozzles should it benecessary to repair, clean or renew the same.

he uses and advantages of my device are thought to be manifest from theforegoing description taken in connection with the accompanyingdrawings. The fire is kindled and fuel placed thereon in the usualmanner.

The draft through the fire will create a suction through the nozzles 3and 5 which will draw fresh air into the ash pit whence itwill risethrough the grate and the bed of the fire, supplying the necessaryoxygen thereto jets 12 and pass through the nozzles 5 and 3 into the ashpit, the flow of said steam from said nozzles creating a strong suctionwhich will draw in a full supply of air so that the fire will quickly bebrought to a white heat and the production of smoke overcome. By the useof my device, soft coal and finely comininuted fuel may be usedadvantageously so that the supply of steam may be maintainedat a verylow cost.

Y The device is obviously simple in its construction and may, therefore,be produced at a very low cost and expeditiously and inexpensivelyapplied to any furnace. Owing to its construction, all the jets andnozzles are readily accessible so that the necessary repairs or allcleaning can be very quickly and conveniently effected. This inventionor apparatus may be made any size with any number of nozzles and may beused for other purposes where a large amount of air is needed, such asin blacksmith shops, as the force of steam through the nozzles is verypowerful and, therefore, takes the place of the .power fan.

Having thus described the invention, what is claimed as new is: V

1. An apparatus for the purpose set forth comprising a casing adapted tobe secured in a furnace wall, a partition in said casing, a plurality oftapered nozzles secured in and extending through said partition, theouter ends of said nozzles having the greater diameters, a plurality ofsupports within the casing spaced outwardly from said nozzles and spacedfrom each other in a transverse plane of the casing, a plurality'oftapered 'nozzles secured in and extending through said supports and eachalined axially with one of the first-mentioned nozzles with its innersmaller end fitting concentrically within and in spaced relation to theouter end of the same, a supply pipe disposed at the outer side of thecasing and extending across the same, a plurality of branches extendinglaterally from the supply pipe'across the outer ends of the outernozzles, jets on said branches each extending into the outer end of oneof said outer nozzles, a retainer at the top of the casing and extendinglaterally therefrom to fit around the supply pipe, and bracketsextending laterally from the lower end of the casing and in which thelowest branches are j ournaled whereby to pivotally support the supplypipe and all its branches and permit the same to swing from the casing.

2. An apparatus for thepurpose set forth comprising a casing adapted tobe secured in a furnace wall, a plurality of axially alined nozzlessupported within said casing, brackets at the lower end of the casingextending laterally therefrom, a central retainer at the top of thecasing projecting laterally therefrom, a steam supply pipe having avertical main portion extending across the end of the casing and aplurality of branches extending laterally across the end of the casing,and jets on said branches extending into'the outer ends of the outernozzles, the lowermost branches being pivotally mounted in the saidbrackets and the main supply pipe passing through-and held by the saidretainer.

In testimony whereof I afl'ix my signature.
